Before You Begin

This section provides you with safety information, technical support

information, and sources for additional product information.

Safety Summary

Your safety is extremely important. Read and follow all warnings and

cautions in this document before handling and operating Intermec

equipment. You can be seriously injured, and equipment and data can be

damaged if you do not follow the safety warnings and cautions.

Do Not Repair or Adjust Alone

Do not repair or adjust energized equipment alone under any

circumstances. Someone capable of providing first aid must always be

present for your safety.

First Aid

Always obtain first aid or medical attention immediately after an injury.

Never neglect an injury, no matter how slight it seems.

Resuscitation

Begin resuscitation immediately if someone is injured and stops breathing.

Any delay could result in death. To work on or near high voltage, you

should be familiar with approved industrial first aid methods.

Energized Equipment

Never work on energized equipment unless authorized by a responsible

authority. Energized electrical equipment is dangerous. Electrical shock

from energized equipment can cause death. If you must perform

authorized emergency work on energized equipment, be sure that you

comply strictly with approved safety regulations.

Sicherheitsübersicht

Ihre Sicherheit ist äußerst wichtig. Lesen und befolgen Sie alle Warn- und

Vorsichtshinweise in diesem Dokument, bevor Sie Intermec-Geräte

verwenden und betreiben. Falls die Sicherheitswarnungen und

Vorsichtshinweise nicht befolgt werden, kann es zu ernsthaften

Verletzungen sowie Geräteschäden und Datenverlusten kommen.

Nicht alleine Reparaturen oder Einstellungen durchführen

Reparieren oder justieren Sie niemals alleine stromführende Geräte. Aus

Sicherheitsgründen muss eine zweite Person anwesend sein, die erste Hilfe

leisten kann.

Before You Begin

viii EasyCoder PD41/PD42 Printer Service Manual

Erste Hilfe

Nach einer Verletzung unverzüglich erste Hilfe oder medizinische

Betreuung aufsuchen. Verletzungen dürfen nicht vernachlässigt werden,

auch wenn sie noch so unbedeutend erscheinen.

Wiederbelebung

Wiederbelebungsversuche müssen unverzüglich eingeleitet werden, falls

jemand verletzt wird und die Atmung aussetzt. Verzögerungen können zum

Tod führen. Bei Arbeiten an oder in der Nähe von Hochspannung müssen

Ihnen die zugelassenen Erste-Hilfe-Methoden vertraut sein.

Stromführende Geräte

Niemals an stromführenden Geräten arbeiten, es sei denn Sie wurden von

einer verantwortlichen Stelle dazu berechtigt. Stromführende Geräte sind

gefährlich. Stromschläge durch stromführende Geräte können zu tödlichen

Verletzungen führen. Falls zugelassene Notreparaturen an stromführenden

Geräten vorgenommen werden müssen, ist darauf zu achten, dass die

genehmigten Sicherheitsvorschriften strikt eingehalten werden.

Safety Information

Your safety is extremely important. Read and follow all warnings and

cautions in this document before handling and operating Intermec

equipment. You can be seriously injured, and equipment and data can be

damaged if you do not follow the safety warnings and cautions.

This section explains how to identify and understand dangers, warnings,

cautions, and notes that are in this document. You may also see icons that

tell you when to follow ESD procedures and when to take special

precautions for handling optical parts.

A warning alerts you of an operating procedure, practice, condition, or

statement that must be strictly observed to avoid death or serious injury

to the persons working on the equipment.

Warnung: Ein Warnhinweis macht Sie auf ein Betriebsverfahren, eine

Praktik, einen Zustand oder eine Anweisung aufmerksam, die genaue-

stens befolgt werden muss, um schwere oder tödliche Verletzungen der

an den Maschinen arbeitenden Personen zu vermeiden.

A caution alerts you to an operating procedure, practice, condition, or

statement that must be strictly observed to prevent equipment damage

or destruction, or corruption or loss of data.

Vorsicht: Ein Vorsichtshinweis macht Sie auf ein Betriebsverfahren,

eine Praktik, einen Zustand oder eine Anweisung aufmerksam, die

genauestens befolgt werden muss, um Schäden oder eine Zerstörung

der Maschine bzw. die Zerstörung oder den Verlust von Daten zu ver-

meiden.

Printer Problems at Power Up

Problem Solution Refer to

Error during printing • Check if the printer is out of media or

transfer ribbon

• Check that the printhead lever is closed

and locked

• If the printhead is closed and locked, but

the problem persists, the headlift sensor

may be out of order. Check connection to

P34 on the main board. Check headlift

microswitch.

• Check if media is jammed/tangled up.

Clear the jam and reload. Clean parts that

may have been exposed to the media’s

adhesive using isopropyl alcohol or a

cleaning card.

• Check the light path between the upper

and lower parts of the label gap sensor to

see if it is obstructed by dust, adhesive, or

stuck labels. Clean using isopropyl alcohol

or a cleaning card.

• Recalibrate the sensors by running a

testfeed.

No printing due to software error • Check to see if a bad command was sent
